Supplement to: Machine learning classification for field distributions of photonic modes

Carlo Barth & Christiane Becker
Electromagnetic modes of photonic nanostructures can exhibit increased near-field energy densities which can be applied in many fields such as biosensing, quantum dot solar cells or photon upconversion. Optimizing such systems enforces to systematically analyze large amounts of numerically obtained three-dimensional field distribution data, as in the presented dataset. The simulated system is a silicon photonic crystal slab on glass (subspace) with a hexagonal lattice of cylindrical holes. The holes are filled with a medium...

E11 - Fast Acquisition Laue Camera for Neutrons (FALCON)

Neutron Laue diffraction is an important method of neutron scattering for measuring single crystals. Laue diffraction patterns are generated in a matter of seconds from very small crystals i.e. <1mm3. FALCON has two scintillating plate detectors coupled to four iCCD cameras each, to produce a 2D projection of a large volume of reciprocal space in a single Laue pattern. Such images can be used to index complex crystal structures, characterise features such as twinning or...

E4 - 2-Axis-Diffractometer

The instrument is primarily suited for magnetic structure determination under various conditions, which includes magnetic fields up to 17 T, temperatures down to 30 mK and pressures up to 10 kbar. The most common application is to reveal spatial arrangement ordered spin structures. Using the polarized neutrons option facilitates the separation of magnetic contributions from nuclear scattering. The measurement of flipping ratios allows registration of very weak magnetic scattering and the mapping of spin density...

V7 - Cold Neutron Tomography and Radiography (CONRAD)

The neutron tomography beam line V7 was designed with two measuring positions: the first one is located directly at the end of the neutron guide, where a very high neutron flux is available but the image resolution is limited due to the beam divergence. The second measuring position uses a pin-hole geometry followed by more than 5m of flight tube in order to gain a high collimation ratio and image resolution. The high-flux measuring position...
